[SUPPORT][JB] CM10, BattOptimization

This Thread is for Optimizing your Battery Life for the ongoing CM10 builds by Quarx, and for my nagging questions.
First you should read about your Battery, and how it calibrates here.
http://forum.xda-developers.com/showthread.php?t=1778492
then I recommend this older Thread of a guy who managed to squeeze out 6 days of juice from his Defy
http://forum.xda-developers.com/showthread.php?t=1022390
His approach is very simple; LessIsMore: no sync, no mobile Data, no widgets, no GPS, bare minimum Apps....
I tried that with Quarx builds, and of course it works. The Downside is, there`s no more shiny stuff on my phone. The good thing apart from increased Battery Life, the OS becomes very fast and a great Testgadget for Quarx work in a minimal environment.
But from here I`d like to dig deeper, and get more Power:
Which System APP`s can be deleted whithout Problems? (I started with trebuchet (nova Launcher) that gives 10MB)
Do you now good alternative APP`s with a low Energy Footprint?
Do you use your phone in any special Battery efficient way? (I have all my non super important APP`s stored as backups with Titanium Backup, and restore them when needed)
WLAN always on?
What other things help with Battery Life on CM10 Jelly Bean?

If LessIsMore, in the way you described it, is the way to go for better battery performance, it will be much more efficient to abandon SMART Phones all together and go back to NOKIA Age.
In today time (21st century) we need to be connected to the net and cloud AT ALL TIME therefore there must be other solution about batteries. Either bigger capacities (RAZR MAXX) or optimized software.
Quarx and the rest from XDA or CM can not help with the hardware (Big capacity batteries) but could optimized the software. I am aware that everyone has different requirement/need BUT there must be a point to start from (may be at least 8 hours (while on work) 3G DATA On (messaging, e-mails), All the goodies (screen related fancy widget, etc.) some Browsing, some Music/Radio) until back home.
And so say (for example): Quarx Rom v.X is out now (and you will be sure that by this set of min. requirement) it will last for at least while on work (typically 8 hours)
It will eliminate half of the question here about "Battery drain and how to overcome it"
At least that is the way I think about all this issues.

I'm not too battery efficient but I am curious as to what I can tweek in the display settings since most of it has some alien jargon. i.e. the Light Sensor Levels...

Ok, here's my current setup I'm reading for battery savings. I think it sets a good balance between efficiency and usability. I'm using Llama to automate all of this.
Data switches on when the phone is unlocked and switches off 2 min after screen off. If I'm at home, the WiFi also switches on with the same settings. When WiFi is connected, data switches off.
When mobile data is on, 2G/3G is on. When the screen turns off or when the WiFi is connected, 2G only.
Sync is disabled, but every hour the mobile data is enabled and it turns on sync and requests update.
I've mucked around with custom auto brightness levels and vsel values as well, and it automatically sets to vsel1 when the screen is off.
Here is my usage from yesterday. This included about 50 min of voice calls.

The screen, and specifically the backlight are major battery hogs.
With this in mind, I'd suggest, if you use your phone mostly at night (like me) then even minimum brightness can be too much...
Use an app like Screen Filter to reduce your brightness levels right up to 0% backlight.
I use the light sensor levels in the day, and at night, when I find the screen a bit too bright, I switch to the lowest sensor level and add a filter of up to 54% or 72%, as need be.
Doing this, I've noticed that screen related battery consumption goes down from 90% with screen continuously on to ~75%.

Can someone share his experience with the sensor levels for the automatic brightness? Also maybe for the other 'automatic brightness' values ..
... apart of the fact that the number of stages has to be changed to save values in the current Quarx Rom

I love my Llama!
I've been looking for something like this since I left the factory supplied motoblur eclair which had some simple data management functions built in. There are literally hundreds of different actions and conditions to personalise. This is sure to extend battery life.
One question. Have you noticed if the app itself uses much battery?
Thanks for sharing... everyone needs a Llama!

The power usage is really minimal. The location method uses the cell id of the tower you are connected to, so does not use additional battery like the Google Location Service or GPS.
Llama is definitely in my shortlist for favorite app.
Also, one of the latest beta release has a profile sharing feature. If I can figure that out I might post some of my profiles.

Verizon took out Battery Saver, here's Qualcomm's solution: Snapdragon™ BatteryGuru

I, and a few other users have noticed that Verizon decided to have HTC strip out their battery saver toggle on the Sense ROM (4.2.2) that ships on VZW's One.
Luckily, Qualcomm provides a standalone application which covers 90% of what the toggle does.
Snapdragon™ BatteryGuru
https://play.google.com/store/apps/developer?id=Xiam+Technologies+Limited,+a+Qualcomm+company
(personally, I haven't found the need to use it yet, but I figured it would help some people)

Thanks man, I was looking for that battery saver mode everywhere, but I guess this will do as well.

Thanks for this info. Anyone know if this is particular app will perform better from more generic battery extenders like Juice Defender?

According to the reviews all it does schedule syncing. Don't know how that is going to save battery...

Battery saver apps are a joke. The only thing I liked about power saver mode was that it cut the CPU frequency down and cut data off after a certain period of time. Other than that, if you need to save more just turn your brightness down, turn off bluetooth, use WiFi as much as possible, and use the phone less.

I normally agree - I realized the other day though, that I don't need background *push* email - but I'd like to have my phone "fetch" email every time I wake it up. Anyone know of anything like that?
(there is a manual setting, but it is when you *enter* the mail app, I'd like it to fetch every time I use the phone.)

Think about how often you "actually" need to have your emails and set it to that. For me, my Yahoo emails I don't need it to check but once hourly. But Gmail is push automatically so I won't mess with that. My corporate email defaulted to push but I often don't need it to constantly update and annoy me so I'm contemplating on 30 min intervals. Setting your emails to longer intervals should reduce that "email stress" that most people seem to endure these days.

The app has low power mode controls.
You can turn off mobile data during inactivity.
Some other features.
It basically gives you battery saver control on any Snapdragon based device.

Lol you could always just use BoneStock ROM. Andy threw the battery saver apk from (can't remember dev's handle. sorry) back in it.

It limits CPU, dims display and disables vibration feedback. Basically everything you can do yourself in stock and if you have a CPU app like SetCPU. Just a one click option that Verizon took out bc they hate battery life I guess idk.

Im running bonestock now, and the power saver has increased my battery life fairly significantly, i'll take that, because at first i wasnt impressed with the battery life, and i watched the ifixit tutorial on how to tear this phone apart to replace a battery, and i want nothing to do with that

Zenphone 2

I have a few questions before I get a ZF2
How is the battery life now ? Did they fixed the battery drain ?
Is Lolipop 5.1 available for this phone ?
Did they improved the camera ? I remember some reviews complaining about the lack of DR in most pictures.
Thank you.

There is no battery drain on this phone. You will always find people complain about battery drain on every smartphone out there.

you should check Android authority's review and tons of people are complaining about the battery life. Maybe you got the phone with an update preinstalled ? That would be a good news !
Are you a moderate user like me ? If you are, how much battery do you have left at the end of the day ?
Thank you

I have it for a month now, got it with an old firmware, now i'm running latest. I get 6 - 7 hours sot over 24 hours. Also, don't use the integrated Asus task killer, battery saver and autostart manager. They only drain battery. I rooted and installed a custom rom that has almost all Asus apps removed but i didn't have battery problems on stock rom either. There is an "android system" that is showing on top of battery usage but it is not a problem for me as it only drains 2-3% over night. I olso turn on data, wifi or gps, only when i need them. I always get top battery life on every smartphone i have, i don't think this is coincidence or luck. The drain is exactly the same as on every other powerfull smartphone on the market.
This phone receives software updates every two weeks and is getting better and better. It just got a new update today if you look in general section. What other oem updates their flagship so often? ?

As previously mentioned, there is no extra battery drain on this phone. It holds up to a good 5-6 hours on daily use. It is an amazing device except for the camera, which is the only bad thing I find about the phone.
Incase you're wondering, ZenUI is AMAZING! I don't know why everyone hates on it, but I've used almost EVERY manufacturer's edition of Android and ZenUI is by far the best. It is the most customizable, it looks the cleanest, and it takes medium amounts of RAM. I say 'medium' because HTC takes A LOT, Sony is whatever, LG is okay, and Samsung takes TOO MUCH.
I feel like ZenUI combines the best in all of the skins and features into 1 neat package that is highly customizable. NOT TO MENTION, you get tap 2 wake STOCK while I had to custom ROM custom Kernel my HTC in order to get a battery hungry and impractical version of it.
Just buy the phone, and make sure to get the 2.3GHz/4GB RAM version.
Enjoy

I'm running stock and get ALMOST what he's getting with stock kernel.
The key is to get root and uninstall/freeze any ASUS apps you don't need/use, install Xposed and use Greenify to freeze apps after they are closed, and finally, set proper battery options such as disabling WiFi & 4G when the screen is off. I need constant email notifications so with the automatic Data Disabling option, I set the GMAIL app as its exception and I continue to get notifications at 10 minute intervals. I assume it disables the networks but re-enables them momentarily and lets GMAIL sync, then disables again. I've never seen this done before especially as a STOCK option.

there is no battery draining (for now) when both are enable anyway, so I dont see why I should turn it off. The battery start draining fast as soon as Im using it. It is by far the worst battery life I ever got.
The good news is I can apparently return the phone at no cost, not even the shipping. I will know more next week. Hurray !

Standby Drain Problem - can't find the reason

Hey guys,
i recently got a HTC 10 cause Ive dropped my Galaxy S7 in water. (insurance)
Besides that the HTC is noticeable faster, the standby drain drives me crazy.
HTC 10 @ Viper ROM with elementalX Kernel
1) What the hell is "BatteryServiceUpdateStats_3"? in 16 hours, it causes over 600 wakelocks per hour. Maybe this is my draining problem? In the Battery Historian screenshot you can see, that my phone is constantly doing something because of this process.
2) Why is there an "unknown" entry at "Kernel Wakeup Reasons"? 287 per hour... wtf?
3) In GSam you can see, that "Android OS (Kernel)" is (always) the top process...

Edit: so i checked Battery Historian with active/inactive WiFi... and what do I see? Yep, much less wakeups from BatteryServiceUpdateStats3 & generally less Wakelock time..... why???

You might have this problem. I have it too and it's infuriating. I've pretty much stopped using WiFi unless I'm charging. Really spoiled my experience with this phone.

Do you have "ok google" hot word detection enabled? That was causing me some serious wakelocks, and I had forgotten I had enabled it to play with, it's usually not something I use or want. I'm still not sold on Google Home being a good thing because google knows everything there is to know about me. I'd rather some devices not know the pitch of my farts or where my girlfriend hides her phone when she has no pockets.
My battery life was still pretty decent though, amazing actually considering it was staying awake and always ready for my next command, but I know with it not running it will be much better.

You could have shown more infos from Battery Historian
If you wanna know what a proper Standby looks like, you can take a look at mine:
http://forum.xda-developers.com/htc...ark-thread-t3376159/post68929720#post68929720
but yeah.... there are a FEW known issues with HTC10 Standby....
A) 4g might cause more Batterydrain than 3G, but that was an early issue, and mainly on American Carriers.
B) WiFi does have shîtload of wakeups you cannot control. ExKernel has wlan_rx and wlan_ctrl divier options, set both to 8 (maximum) might help.
C) If you have Access to your router, maybe deactivating IPv6 can reduce WiFi Battery Drain.
To your 3 Questions.....

Power Nap [Xposed Module] also blocks them. But it doesn't matter. Because they do not wake the phone, they happen when the phone gets awaken by something else.
Check this out (With Power Nap enabled and What's app excluded)
As you can see, almost no Userspace Wakelocks:
As always Google Services is the only thing you simply cannot shut up, no matter what
But yeah, the Problem is on the Kernel Level....
You see a Normal Wake due to an UserSpace Wakelock:
And one that's happening due to Kernel:
So as long as you have these Kernel wakes, the BatteryServiceUpdateStats_3 will activate at the same time. Batterylife itself is not really affected.

What does the Battery Historian say about CPU usage by App?

Hi, did you find any solution? same thing is happening in my lenovo k6 power but only when i use jio sim. if i don't use sim there is no battery drain in standby. check my attached screenshot of battery historian.

Hi try to reinstall other kernel, im using CleanSlate v2.2.0 now so far superb. and also install htc bost to sure not eat so much RAM usage.
Last time using elemental kernel but im lazy to configure, therefore battery drain quite fast even in standby mod.

battery drain

So I'm not going to lie... I'm hating this phone.
Camera is awful and now I'm getting massive battery drain.
I was at 100% and unplugged at 2am by 7am without any use at all my battery was down to 89%. I've found the battery stats but it doesn't add up.
Is there anywhere I can see the hardware usage?
So far I've dropped the screen refresh to 60htz, resolution to HD, dark mode on, always on is off, tap and lift to wake are off.... my 2 Yr old phone didn't drop this much!
Can anyone help? I'm really trying to salvage something from this phone but if the camera issue isn't sorted by Samsung and I can't get more than half a day battery out of it I fear this maybe the biggest waste of money ever

so in 30 mins of being unplugged on a full charge, not being touched or used at all the battery has dropped by 3%

Exynos ?
Sent from my a40 using XDA Labs

same here - i dropped rez from 120 FHD to 60 FHD thinking is going to improve but had the same battery life - so it doesnt look like its the refresh rate but rather something in the background - could be phone trying to find a 5g signal - as am outside - DK - still is rubbish

exynos990. can i turn the 5g off?

Samsung unfortunately still failed to optimize its Exynos processor so you have to manually sort everything out .. all the apk that don't need have disabled and ones i use less have put into a deep sleep... 96Hz refresh rate, 70% brightness, sync., location etc.all on ...WiFi/data 80/20%... all under ideal conditions, at home (due to self-isolation) .... and after that it looks like this...S20 Ultra-Exynos

2. Go to settings >> Device care >> battery >> app power management..
- here you can put the app to deep sleep etc...
...... do this ... for now [emoji3]

So iv installed a battery monitor and the screen is using around 1% every 4 mins. I'm on dark mode, 60hz refresh, auto brightness, HD+

So far I've dropped the screen refresh to 60htz, resolution to HD, dark mode on, always on is off, tap and lift to wake are off.... my 2 Yr old phone didn't drop this much!
Can anyone help? I'm really trying to salvage something from this phone but if the camera issue isn't sorted by Samsung and I can't get more than half a day battery out of it I fear this maybe the biggest waste of money ever

I have s20 Exynos 4G and was also shocked by the battery initially. Some things that helped:
- Did a factory reset and setup everything manually, with data moved by Samsung Switch battery was dying in 2.5 hours
- Disabled Edge panel, seems it used location a lot
- Put Facebook into deep sleeping apps
- Turned off AOD
After the above, my phone is reaching 4.5-5 hours SOT, display at [email protected]

I was thinking of the next phone I buy as I doubt if manufacturers like Samsung will debloat their OSs as much as we want, so being able to disable some apps is useful.
I did it on my stock S5 years ago, just one of those things I had forgotten to do on this as it's only a few days old.
